Dear Mr and Mrs Smith!
Thanks for reserving a room for me and John.
Due to your help, we had no problems in getting the room. We liked it very much. It's very convenient and not far from the sea.
Our neighbors are English-speaking, so we are sure to improve our English. I hope we'll have much practice.
By the way you can visit us next Sunday. We'll have a lot of free time and I like to see you at our place. I think we'll have a wonderful time.
We are looking forward for your coming. Thanks once more for your help.
I hope we'll see you on Sunday.
Bye bye, Mary and John. .
